Patented Feb. 20, 1912. Serial No. 659,911.

To all whom it may concern:

Be it known that I, JOHN F. MURPHY, a citizen of the United States, residing at Bridgeport, in the county of Fail-field and State of Connecticut, have invented certain new and useful Improvements in Combined Hot and Cold ater Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and use the same.

My invention relates to combination hot. and cold water alves adapted for sinks, wash bowls and bath tubs wherein a single valve is adapted to supplyhot and cold water separately or commingled, and is also adapted to discharge different kinds of liquids, or a mixture of the same.

Referring to the drawings wherein the same figures and letters of reference indicate like parts in the several views,Figure 1 is a reduced upper plan view of the valve and its two inlet. branch pipes integral therewith; Fig. 2 is a reduced side elevation of the valve; Fig. 3 is an enlarged end view of the valve plug and broken view of the valve body and inlet branch pipes; Fig. 1 is an enlarged central sectional view of the valve body and broken view of the inlet pipes on line 4 l of Fig. 3; Fig. 5 is an enlarged central sectional view of the valve body on line 5 of Fig. 1; Fig. 6 is an enlarged detail elevation of the valve plug; Fig. 7 is an enlarged detail elevation of the valve plug looking in the direction of arrow a of Fig. (i; Fig. 8 is an enlarged detail elevation of the valve plug looking in the direction of arrow 0 of Fig. 7; and Figs. 9, 10, ll, 12 and 13 indicate crosssections of the valve plug on line 0 0 of Fig. 6, and of the valve body on line (I of Fig. 4, showing the different positions of the plug with respect to the ports of the valve body.

The valve body 1 has the two inlet branch pipes 2 and 3 integral therewith whose outer threaded ends are adapted to be attached to incoming cold and hot water pipes (not shown) over a sink, wash-bowl or bath tub. The valve body is provided with the hot water inlet port- 4 opening into the branch 2, and the cold water port 5 opening into the branch 3.

6 is an upper outlet port for cold or hot water located on the quarter and is on a line with the ports 4 and 5. The lower outlet port- '7 is located directly under the port 6 for the outletof both hot and cold water at the same time, and 8 is the mixing chamber located in the valve body extension 8", and 9 the final discharge port.

The plug 10 is provided with the recess or passage way 11 adapted to register with the ports 4, 5 and 6.

12 is a spiral or angular recess or passage on one side of the plug whose upper end is adapted to register with the port t, and its lower end with the port 7, while the upper end of the opposite spiral recess or passage 13 is adapted to register with the port 5, and its lower end with the port 7.

In Fig. 9 it will be observed that the loca tion. of the plug is such that all of its recesses or passages are shut off from all of the ports of the valve body. Let it be supposed that the port- 4 admits hot water, and the port 5 cold water. Now, turning the plug until one edge of recess 11 registers with the port 5 with the other edge of said recess uncovering port 6, cold water will flow from port through port (3, as shown at Fig. 10, into the mixing chamber and from thence through the discharge port 9, Fig. 5. Turning the plug an equal distance in the opptr site direction as shown at Fig. 11, hot water will flow through ports 1 and G in the manner as described for cold water. 'lurning the plug into the position shown at Fig. 12, will bring the upper end of recess 12 in register with the cold water port and the lower end of said recess to register with the lower port 7, Figs. 4 and F, and, at the sanic time, the recess 11 of the plug will be in position to uncover the port at, which, as before mentioned, will allow the hot water to enter and pass out of port (3 and mingle with the cold water in the mixing chamber 8. Turning the plug into the position shown at Fig. 13 will simply reverse the process described for Fig. 12, viz.: the upper end ofthe recess or passage way 13 of the plug will register with the hot water port 4:, and its lower end with port 7, and the recess 11 of the plug will uncover port 5 for the admission of cold water.

Any well known means may be employed for operating the plug and for indicating its several positions. I have shown the handle 14, Fig. 2, adapted to be mounted on the square end 15 of the plug. On the underside of the handle is the well known housinglG carrying the'spring pin 17 adaptr ed to register with notches e f g h i, Fig. 3, located in the upper edge of the valve body. When, therefore, the spring in is in notch g, the valve will be closed; in notch f, hot water; in notch h, cold water; while either notch e or 72, will give a mixture of hot and cold water.

The peculiar construction of the valve above described renders it particularly adapted to give full open inlet and outlet ports for both hot and cold water separately, and especially so when hot and cold are mixed, in which case both hot and cold water inlet and outlet ports can be full open, or either the hot or cold Water ports may be throttled so as to admit more hot water than cold, or vice versa.

Having thus described my invention, what I claim is 1. In a valve of the character described comprising a body having branch pipes for the admission of hot and cold water integral therewith communicating with ports in the valve body, said valve body having upper and lower outlet ports, a plug for the valve body having a recess adapted to register with either inlet port and the upper outlet port, said plug having oppositely located angularly disposed recesses adapted to register with the respective inlet ports and the lower outlet port of the valve body.

2. The combination with a valve body having hot and cold water inlet ports, upper and lower outlet ports, said upper outlet port on a line with the inlet ports, of a plug having a recess adapted to register with either inlet port and the upper outlet port, and oppositely located side recesses adapted to register with the respective inlet ports and the lower outlet port of the valve body.

3. In a valve of the character described comprising a body having an extension pro-. vided with a mixing chamber and a discharge port, said body having hot and cold water inlet ports, and upper and lower outlet ports communicating with the mixing chamber, a plug having a recess adapted to register with either inlet port and the upper outlet port, and oppositely located recesses adapted to register with the respective inlet ports and the lower outlet port.

In testimony whereof I aflix my signature in presence of two witnesses.
